AddictionTue, 03 Mar 2015 16:18:51 ESTnews344621924New compound protects 100 percent of ferrets, mice, from H5N1Since 2003, the H5N1 influenza virus, more commonly known as the bird flu, has been responsible for the deaths of millions of chickens and ducks and has infected more than 650 people, leading to a 60 percent mortality rate for the latter. Luckily, this virus has yet to achieve human-to-human transmission, but a small number of mutations could change that, resulting in a pandemic. Now a team of investigators from St. Jude Children's Research Hospital, Stanford University Medical Center, and MacroGenics have developed an antibody which has proven 100 percent protective against the virus in two species of animal models. The research is published ahead of print February 11, in the Journal of Virology.http://medicalxpress.com/news/2015-03-compound-percent-ferrets-mice-h5n1.html
